**P/N: 2450AT14A0100001T Legacy P/N: 2450AT14A0100** 

## **2.44 GHz RF Chip Antenna** 

- 2.4 – 2.48 GHz pass band 

- IEEE 802.11, Wi-Fi, WLAN, IoT 

- Mini SMD, EIA 0603 

- Corner mount 

- RoHS compliant 

Johanson Technology, Inc. (JTI) miniature RF ceramic chip antennas are made using Low Temperature Co-fired Ceramic (LTCC) technology which has the ability to embed low and high dielectric constants inside our antenna. This  enables our components to have high detuning resilience and stability over extreme temperatures (~2ppm).
